What structure determines the overall texture of hair?

The diameter of the hair strand is the key determinant of the overall texture of hair. Texture refers to the feel, appearance, and behavior of hair, often categorized as fine, medium, or coarse. The diameter influences how the hair reacts to various styling techniques and products. For instance, finer hair tends to be more delicate and may be more susceptible to damage, while coarser hair often has a stronger structure that can handle a variety of styles and products.

Additionally, hair texture can affect the way light reflects off the hair, impacting its shine and overall aesthetic. Understanding the diameter and its relationship to hair texture is crucial for cosmetologists when selecting appropriate hair care products and providing styling recommendations tailored to an individual’s specific hair type.
